What Is This Tool?
This converter transforms power measurements given in pound-foot per hour, an imperial unit for slow mechanical work rates, into hectojoules per second, a metric unit commonly used for electrical and thermal power ratings.
How to Use This Tool?
-
Enter the power value in pound-foot/hour (lbf*ft/h) into the input field
-
Select pound-foot/hour as the source unit and hectojoule/second as the target unit
-
Click the convert button to get the equivalent value in hectojoule/second (hJ/s)
-
Use the result to understand power in metric terms applicable to electrical and heating equipment
Key Features
-
Converts very low mechanical power values from legacy imperial units to modern metric units
-
Useful for vintage equipment, small mechanical systems, and laboratory device power ratings
-
Performs accurate unit translation based on established conversion rates
-
Browser-based and easy to operate with straightforward input and output fields
Examples
-
10 pound-foot/hour = 0.000037661609675818 hectojoule/second
-
100 pound-foot/hour = 0.00037661609675818 hectojoule/second
Common Use Cases
-
Expressing very low continuous mechanical output in imperial units
-
Documenting or restoring historical machinery specifications
-
Estimating hand-crank or slow winch power and converting it into metric units
-
Specifying small electrical appliances and lighting powers in metric units
-
Reporting power for motors or laboratory devices using convenient metric multiples
Tips & Best Practices
-
Ensure the input value represents mechanical power in pound-foot per hour correctly
-
Compare converted results against expected power ranges for accuracy
-
Use the tool for low power values where imperial to metric conversion aids clarity
-
Be mindful that the converted metric values are often very small numbers
-
Use appropriate numerical precision when working with tiny converted values
Limitations
-
The pound-foot/hour unit is very small compared to hectojoule/second, yielding tiny converted values
-
This conversion is generally practical only for very low power levels
-
High-power calculations with this conversion may not be useful or feasible
-
Accurate results require careful numerical handling or instrumentation due to small magnitudes
Frequently Asked Questions
-
What does pound-foot per hour measure?
-
It measures mechanical power at a very low rate in imperial units, quantifying work done at one foot-pound force per hour.
-
Why convert pound-foot/hour to hectojoule/second?
-
To translate low-rate mechanical power from legacy imperial units into a metric unit useful for electrical, heating, and scientific applications.
-
Is this conversion suitable for high power values?
-
No, because pound-foot/hour represents very small power, the converted values are extremely tiny and not practical for high-power scenarios.
Key Terminology
-
Pound-foot per hour [lbf*ft/h]
-
An imperial unit of power representing one foot-pound force of mechanical work done per hour, used to express very low continuous mechanical output.
-
Hectojoule per second [hJ/s]
-
A metric power unit equal to 100 joules transferred or converted per second, equivalent to 100 watts.
-
Conversion rate
-
The factor used to translate values from pound-foot/hour to hectojoule/second: 1 lbf*ft/h equals 0.0000037661609675818 hJ/s.
